AbstractArteriovenous fistulas for hemodialysis create a leftto-right shunt, resulting in an average 25% increase in cardiac output and subsequent remodeling of cardiac chambers. Some of these patients may develop highoutput heart failure. In this report, we present two cases of heart failure associated with an arteriovenous fistula for hemodialysis, each showing distinct clinical outcomes following either its occlusion or cerclage. Drawing from existing medical literature, we explore potential causes that might account for the divergent clinical courses observed in these cases.
